## Minestarters Atlas summary

Radisson Mining Resources has reported high-grade gold drill results from its O'Brien Gold Project in Quebec, notably extending mineralization to a record depth of 1.9 km. The results include several high-grade intercepts, such as 20.39 g/t Au over 1.5m, confirming the continuity of a high-grade vein system beneath existing resources.

Reasoning: The announcement reports significant high-grade gold intercepts at record depths \(1.9km\), extending the known mineralization footprint well below the previous resource limit.

- Positive factor: Significant depth extension to 1.9km

- Positive factor: High-grade intercepts in new pilot hole

- Positive factor: Step-out drilling success rate of 79%

- Positive factor: Continuity of high-grade vein system demonstrated

Facts used in scoring: 5

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Results extend mineralization 350m below the current limit of mineral resources.

Evidence · text

> extend the scope of gold mineralization beyond the Company's recent updated March 2026 Mineral Resource Estimate

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Intercept of 20.39 g/t Au over 1.5m is exceptionally high-grade for this deposit type.

Evidence · text

> 20.39 g/t Au over 1.5 metres

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: Release mentions MSALABS, ISO/IEC 17025 accreditation, and use of blanks, duplicates, and CRMs.

Evidence · text

> Standard reference materials, blank samples and duplicates were inserted for quality assurance and quality control.

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Mr. Richard Nieminen, P.Geo, \(QC\) is named as the Qualified Person supervising the release.

Evidence · text

> prepared under the supervision of Mr. Richard Nieminen, P.Geo, \(QC\)

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
